@sebastian_paul @Broma07983148 @djvanness That 50 million is probably an estimate, not counted.
On a similar basis, the estimates for covid are much higher than the 500M counted. Probably most of the world, >5B.
Covid has spread faster and infected more than flu. Most people get flu once every 5-10 years.
@塞巴斯蒂安·保罗@Broma07983148@djvanness，5000万可能是一个估计数，不算在内。
在类似的基础上，新冠病毒的估计数远高于5亿人。可能是世界上大多数地方，>；5B。
新冠病毒的传播速度比流感更快，感染率也更高。大多数人每5-10年患一次流感。
